Embodiment 1

[0018] see Figure 1-4 , this embodiment includes a screw 1 and a nut that cooperates with the screw 1, the top of the threaded section of the screw 1 is provided with an outwardly protruding round table 3, and the side wall of the round table 3 is evenly provided with a number of pointed points arranged along the length direction of the screw 1 Teeth 2; the nut includes a body 4, one end of the body 4 is provided with an extended expansion section 5, the end face of the expansion section 5 is provided with a positioning hole, the inner wall of the positioning hole is provided with a positioning groove 7 matching the tine 2, and the screw rod 1 When tightly fitting with the nut, the round table 3 passes through the positioning hole and cooperates with the positioning groove 7 through the tines 2 to prevent loosening.

[0019] like Figure 4 As shown, the tine 2 in this embodiment is an isosceles triangle, and the positioning groove 7 is an isosceles triangle matching the tine...

Embodiment 2

[0022] see Figure 5 , the structure of this embodiment is basically the same as that of Embodiment 1, the difference is that the tines 2 are helical teeth, the inclination direction of the helical teeth is opposite to the direction of rotation of the screw 1, the top of the helical teeth is inclined clockwise, and the screw 1. Rotate counterclockwise when tightening. When the screw 1 is tightened, the long side of the helical tooth acts as a guide to make it easier for the round platform 3 to enter the positioning hole. The short side of the helical tooth cooperates with the positioning groove 7 to more effectively prevent the reverse direction of the screw 1. rotate; see Image 6 In this embodiment, the top of the expansion section 5 is provided with an expansion tool positioning groove 8 for loading the expansion tool when the bolt is loosened.

Abstract

The invention relates to an anti-loosening bolt assembly which comprises a screw rod and a nut matched with the screw rod. The top end of a thread section of the screw rod is provided with a circulartruncated cone protruding outwards, and the side wall of the circular truncated cone is uniformly provided with a plurality of sharp teeth arranged in the length direction of the screw rod; and the nut comprises a body, one end of the body is provided with an extended expansion section, the end face of the expansion section is provided with a positioning hole, the inner wall of the positioning hole is provided with positioning grooves matched with the sharp teeth, and during fastening and matching of the screw rod and the nut, the circular truncated cone passes through the positioning hole, and the positioning grooves are matched with the sharp teeth for preventing the screw rod and the nut from getting loosened. The anti-loosening bolt assembly has better looseness resistance and improvesthe reliability of fasteners.

Description

technical field [0001] The invention relates to the field of design and manufacture of bolts, in particular to an anti-loosening bolt assembly. Background technique [0002] The existing ordinary bolt assembly is generally composed of a screw, a spring washer, and a nut. This ordinary bolt assembly can be used for parts with low fastening requirements, and the working environment of some parts has higher frequency vibration. Such as vibrating screens, airplanes, high-speed rail, automobiles, etc., the fastening requirements of the joint parts are high, and anti-loosening bolts must be used. The existing anti-loosening bolts generally use two or more nuts to achieve anti-loosening effect, but this kind of In the actual use of the structure, if the collision or vibration is strong, it may still cause loosening, and the reliability is insufficient. Contents of the invention [0003] The main purpose of the present invention is to solve the problem that the existing bolt asse...
